It was April 1954. A website says: "Across the United States, 1.8 million
"Polio Pioneers" in grades one, two and three in 44 states took part in the
trial over the course of a year. The following year, the Salk vaccine was
declared "safe, potent and effective." http://health.yahoo.com/news/34664
It also verifies that it was an injection, as remembered by a doctor who
gave it. Another site says "The Salk vaccine was the first type of polio vaccine
to become available. It was made by cultivating three strains of the virus separately
in monkey tissue. The virus was separated from the tissue, stored for a week,
and killed with formaldehyde. This killed-virus vaccine was given by injection and
required 4 "shots."http://www.freemedicineprogram.com/healthcare/Polio+vaccine%2C+Salk
